This 'nvention has for"ts object the production of'a bark rossing machine which is particularly simple in construction, and highly efficient land rapid in operation; .and

the invention consists 1n the combmations and constructions hereinafter set forth. and

claimed..

This bark rossing machine. comprises, genorally, a rotating member having a"passage through which the branches are passed, means carried by said memberjjand` projecting into the passage to remove the bark, mea-ns for carrying away the removed bark from one end of the passage of said member, means .'for feeding the branches through the passage, and Ineensl for actuating the .feeding means, the rotating member and `the means forcarrying away the removed bark. However, some of the foregoing parts may be omitted if desired. 1 is the frame of. this machine, which may boef .anydesirable form, size and construe! 2 designates thefrotating member having' an axial passagel 3 through, which the branches are passed, the member. 2 havlnga hub4'detachably secured as by screw threads tofthe body of said member` 2, and thish'ub being journaled in a.` suitable bear1ng 5 formed-in a--isupporting bracket 6 supported by the frame 1 `near the front side thereof.

.mon power shaftrand aldescription of one set of mechanism will be suiicient for both. The means carried byf'the'member 2v and projecting into Athe passage 3 for removingl the bark' from the branches comprises prefferably a pair of jaws 8 projecting'into the` passage 3 near` the receivingy end thereof,

these jaws being here shownv as sliding m radially extending guides 9 formed inthe front face of the member r2 and'- as being pressed toward each otherl by springs' 10. 1des 9 are covered by suitable plates 11 which are held in position by "screws 12.'

The jaws are formed with faces 13 inclining` from their outer sidesvtoward the 'center of the passage and terminating in edges 14 which normally meot` in a. straightlinecross# ing the passage and engage thebranches, these faces 13 facing outwardly in order to engage the advance endsof the branches be ing passed into 'the passage 3. The faces. 13' act together as a funnelto guide the branches tween the jaws 'as the branches Vare being pushed into the passage 3, said' faces 131 forming comparatively sharpf edgeson the opposing faces of thel jaws 8; and owing-l to the rotation pf the member 2 carrying the jaws 8, the edges vloosen 'the bark,"and owing.

to the feeding movement ofthe ybranches' through the passage 3 theloosened bark isv scraped o. v

the heads of the jaws toward`eachotheri"` The means for carrying away the removed bark from the entrance end of the passage 10 are located in lengthwise,- slots 15 in the bodies 'of the jaws and4 eachv spring is interposed between one enelI ofthe corresponding slot 15 and a pin 16 project-- be arranged withtheir heads'y being movable toward the other across the passage to grip Vthe removed bark, at the e11- trance end of the passage, between the same vand the other member, and the two members being then movable'downwardly together until the bark has been carried away from .the member 2, and said two members then separating permitting the bark to drop beneath the machine, whereupon the gripping members are returned to their normal position. 1 y

The gripping members consists of jaws 17 and 18 carried respectively by reciprocating parts 19, 20 extending upwardly, the support for the upper jaw 17 being connected to a lever 21, Fig. 1, pivoted between its ends at 22 to a suitable bearing supported bythe frame 1, this lever 21`hav1ng an arm 23 arranged to be engaged by the power driven means to be described, and another arm 24 to which is connected a returning weight 25. The other support 20, is connected at its upper end to a returning spr'm 26 suspended from a yoke' 27 at the top o the frame of the machine. l In operation, the jaw 17 is moved downwardly by the lever 21 across the passage 3 and grips the accumulated bark between its lower edge and the upper edge of the jawV 18 whereupon the downward movement of the jaw 17 is transferred to the jaw 18 until' the jaw 18 engages a stop 29 provided on the frame, Fig. 3, whenthe weight 25 is permitted 'to raise the upper jaw and hence separating the jaws and permittin the bark to drop. The weight 25 and sprlng 26 then return the jaws to their starting position. The weight 25 is arranged to act quicker than the spring 26 so that the upper jaw will open faster than the lower jaw will close. The jaws 17 and 18 are controlled and timed in their operation bythe projection 67 on the. wheel 66 and the operator inserts thev branch between the jaws 8 immediately after the jaws A17 and 18 have opened and as there is but one projection 67 and the wheel 66 is large and revolves comparatively slowly, lthere is ample time for the branch to pass through the member 2 before the jaws 17 and 18 again close. The

jaws 17 and 18 for both rotating members 2 inthe double construction here shown are supportedby one set of supports 19 and 20. The means for feeding the branches into 31 arranged in front of the passage 3, the rollers being arranged at an angle, usually at a right angle to eachother, and the planes coincident with the points of tangency of the pairs intersecting in a line substantially coincident with the axial line of the passage 3. A guide asa tube 32 is also arranged in advance of these rollers with its axis alined with the axial line of the passage 3. The

'means for feeding the rollers also includes means for drawing the branches through the passages, this means including two sets of lrollers 33 and 34 spaced apart, and a tube 35 interposed between the pair of rollers and arranged with its axis substantially coincident with the planes of tangenoy of therollers 33 and34. and with the axis of the passage 3.

The actuating means includes a power shaft 36 journaled in suitable bearings in the frame, and power transmitting means between this shaft and the various moving parts of the machine.

The lower-transmitting means between i the sha 36 and the rotating members 2 includes a sprocket wheel 37 mounted on said shaft and connected by a sprocket chain 38 to a sprocket wheel 39 mounted on a shaft 40 jcurnaled in a suitable bearing locatedv directly above one of the members 2, additional sprocket wheels 41 on the shaft 40 and connected by sprocket chain 42,-Fig. 3, to the sprocket teeth 7 on the hub 4 of the member 2.

' 'The motion from the shaft 40 is transthe other member 2, by means of intermesh- `mitted to a. similarA shaft 43 which drives ing gear wheels 44 and 45 mounted on the L -shafts 40 and 43 respectively, vand the shaft 43 is connected to its corresponding member 2 by a sprocket wheel and chain 41 and 42.

The vertical feeding rollers 30 are driven .from the power shaft 36, by means of a sprocket wheel 46 on said shaft 36 and connected to a shaft 47, journaled in a bearing v in the lower part of the frame, by means of a sprocket chain 48 running over the wheel 46 and a sprocket wheel 49 'onthe shaft 47, and the sha-ft 47 is connected to the first set of vertical rollers by means of a beveled gear 50 thereon meshing with the beveled gear 51 at the lower end of a vertical shaft 52 journaled in suitable` bearings in lthe frame, and having 'a power-transmitting4 wheel as a pulley at its "upper end which is connected by a belt 54 to a pulley 55 mount- -ed'o'n' the upper end of the axle 56 of one of the rollers 30 of the Iirst set of vertical rollers, the motion of the axle 56 being transferred to the axle 57 of the other roller by intermeshing gears 58 and 59. The axle 56 is connected tothe axle 56 of'one of the other vertical rollers by means of pulleys 60 and 61 mounted respectively, on said laxles and a belt 62 connecting the pulleys; and the rollers 30 4of the second set are connected by gears similar to the ears 58 and 59.

The horizontal r'oers 31 are rotated by means of a beveled gear 63 mounted on the axle of one of said rollers 31 and meshing with the beveled gear 50,'and the axles of the rollers 31 are connected by gears'64 and 65, j

The shaft 4:7 extends from front tp re'ar of the machine and is provided with two additional beveled gears 50 located inposition to mesh with the beveled gears 63 mounted intermeshing 'on' the ends of the lower rollers-of each pair Thevmeans for actuating the lever 21 to .depressy the jaws 17 and 18 comprises a wheel 66 havin a cam or projection 67 on one side thereo arranged to pass under. the

arml 23 of the lever 21 and .hence Vraise-the rear end of the lever against the action of the weight 25 and depress* thefront end of said lever to e'ect the operation of the jaws 17 4and,18 as described. The wheel 66 is op erated with'sprocket teeth and-is connected to a sprocket wheel on theshaft 47 by a chain 68.
